How could I create custom commands based on text? Like, say I have a textbox, and in the textbox is this: "say Hi". When I press the "Execute" button, it will do this: "MsgBox("Hi")"... Kind of like a custom scripting language... I want my application to support scripting, but I want the syntax to be simple... How do I go about doing this?

I am using custom textboxes and I need to be able to set the Text on txb1 based on the Text of txb2. I have simplied my code to the following:
Public Class customtextbox
Inherits TextBox
Public Event ControlReset()
[Code]....
So, when txb1 looses focus, if its Text is "fried", then it sets off txb2's ProcessAlert function. I had tried to change the value of txb2 Text in ProcessAlert function, but didnt work, so I tried to get it to raise an event instead, which then tries to set the Text property. However I still cant set txb2's Text property. The Text property seems to be set for the duration of the "life" of the Event handler. When I step through the forms controls within the Event handler, the changed Text value is there, but not outside of the Event handler.
I am attempting to create a rudimentary text editor with buttons that can implement the Cut, Copy and Paste commands. I was able to use buttons on a toolbar and menu to implement the Cut, Copy and Paste commands using the "Command="Cut"" command in the XAML of the buttons on the toolbar and menu but have been unsuccessful in using regular buttons to implement the commands. When I attempted to use the "Command="Cut"" command for regular buttons the buttons appear disabled when debugging the application. Does anyone know if the Cut, Copy and Paste commands are disabled for regular buttons?
View 2 Repliesit is possible to create a class based on text box, add some code to its events, say gotfocus event, and visually add this textbox to a form instead of adding it in code. Just like we drag and drop a textbox to a form from toolbox.
View 5 RepliesI wrote a program that read a text file, find some specific text and eventually replace it with other. This works fine but after the file creation I have to ftp MANUALLY to my AS400, putting the file and finally run a specific command.
Here's the question, I saw that I can use FtpWebRequest but it only permits to download, upload and so on, I need to run a custom command (passing a string).in other words here's what I need:
user = "me"
pass = "you"
host = "as400"
ftp.Credentials = New System.Net.NetworkCredential(user.Text, pass.Text)'now the connection is opened put my file send custom command

I want to create a custom control that has a cursor like a regular text box, I tried using a line and a timer that makes the line 'Blink', but that wasn't too reliable because I had to change the location and background in the timer... I guess I could do it, but I wanted to ask my question here.
Basically what I am doing is creating a custom control to allow inputs as in fractions, sub/superscripts, etc.... The TextBox Control doesn't support text in that many locations.

View 2 RepliesI am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

View 7 RepliesHow do I create commands that allow a group of adjustable voltages to be provided outside the computer, via the usb, serial or paralell ports, etc to control devices connected to the computer?
As a former electronic technician and developer, I have several useful projects I would like to develop.For example, I just received a celestron digital microcope and I am interested in developing a speciman stage the microscope can be placed in which provides a from 4 to 8 adjustable led's located above the speciman and more below the speciman so the lighting on the specimen can be adjusted in a variety of ways so hidden features of the specimen will be revealed when viewed from the microscope.

I am using a list to keep track of a number of custom Row objects as follows:
Public Rows As List(Of Row)()
Row has 2 properties, Key (a String) and Cells (an ArrayList).
I need to be able to sort each Row within Rows based on a developer defined index of the Cells ArrayList.
So for example based on the following Rows
Row1.Cells = ("b", "12")
Row2.Cells = ("a", "23")
Rows.Sort(0) would result in Row2 being first in the Rows list. What would be the best way of going about implementing this?
I have this which is exporting the SDK info to a txt file. I would also like to export the processes that are running to the same text file.
Dim sdkCommand As String
sdkCommand = "C:WindowsSystem32Java.exe -version 2> C:UsersJavaSDKInfo.txt"
Shell("cmd.exe /c" & sdkCommand)
End Sub
If I try adding this to it, I am only able to still see the output from sdkCommand, but nothing about the tasks that are running. I am assuming I need to combine the shell statements?

View 1 RepliesWith VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file
I need to build an forms app that 'posts' or 'sends' text commands to an external console process, called Minecraft Server It is a java-based process, filename 'minecraft_server.jar'. Run by my computer via 'java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui'. The Process ID I assume would change each time it's run. This process can be downloaded here: [URL]
I am guessing that I need to:
1) find the Process ID for it, based on its process details, such as Command Line
2) figure out a way to 'post' these commands, commands such as "stop" into the console window
I cannot have this process launched by my VB project.
Tell me older versions of these commands to be used with .NET 1.1?

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?
